Description

Technical Field

[0001] The utility model belongs to the technical field of wheel hub processing, and particularly relates to a wear-resistant automobile wheel hub bearing surface polishing device. Background Art

[0002] Automobile wheel hub bearing is one of the important parts of automobile. It is mainly installed between the automobile wheel hub and the axle, supporting the wheel hub, reducing friction and ensuring the smooth rotation of the wheel hub. The wheel hub bearing is usually composed of an inner ring, an outer ring, rolling elements and a cage. The inner ring is tightly connected to the axle, and the outer ring is connected to the wheel hub. The rolling elements are generally steel balls or rollers, which roll between the inner and outer rings, greatly reducing the friction resistance during rotation. During the driving process of the car, the wheel hub bearing bears the weight of the vehicle and forces from different directions, such as acceleration, braking, steering, etc. High-quality wheel hub bearings have good sealing performance, which can effectively prevent dust, moisture and impurities from entering, extending the service life of the bearing. Its performance directly affects the driving stability, handling and safety of the car.

[0003] At present, in the process of processing automobile bearings, it is necessary to polish the outer surface thereof. For example, the Chinese patent with the announcement number "CN221560903U" discloses an automobile bearing production polishing device, which includes a polishing box, the four corners of the bottom of the screw sleeve polishing box are connected with support legs, the rear side of the screw sleeve polishing box is provided with a dust suction mechanism, the screw sleeve dust suction mechanism is used to remove dust generated during the bearing polishing process, the bottom of the inner cavity of the screw sleeve polishing box is connected with a connecting plate, the bottom of the inner cavity of the screw sleeve connecting plate is provided with a clamping mechanism, the screw sleeve clamping mechanism is used to stably clamp the bearing during the polishing process, the bottom of the screw sleeve connecting plate is provided with a slide groove, the screw sleeve dust suction mechanism includes a dust collector, the bottom of the screw sleeve dust collector is connected with a dust outlet, the top of the screw sleeve dust collector is connected with a dust suction pipe, and the top of the screw sleeve dust suction pipe is connected with a filter shell. The automobile bearing production polishing device provided by the utility model solves the problem that the existing device does not have a clamping function and dust suction;

[0004] During actual use, the above-mentioned device can indeed achieve a certain polishing effect. However, during the polishing process, most automobile wheel hub bearings are arranged in an annular structure. Usually, the inner wall and outer surface of the bearing annular parts need to be polished simultaneously to meet high-quality production requirements. However, it is obvious that the existing above-mentioned device cannot achieve synchronous polishing of the inner wall and outer surface of the bearing parts during the processing process. This results in the need to perform separate polishing operations on the inner wall and outer surface respectively during the processing process, which not only increases the processing time and process steps, but also reduces production efficiency. For example, in the traditional processing method, the inner wall is polished first, and then the outer surface is polished. In the meantime, operations such as flipping and repositioning of the parts are required, which is not only cumbersome but also prone to errors. It can be seen that the existing device has obvious inefficiency problems when processing annular parts such as automobile wheel hub bearings, so it is urgent to improve and optimize it.

Then the fourth motor is started to drive the polishing wheel to rotate at high speed. The two polishing wheels can polish the inner and outer walls of the bearing respectively, which greatly improves the polishing performance of the device and provides a strong guarantee for efficient and high-quality bearing processing.

[0031] Principle and advantages of use: By setting up the clamping mechanism 2, the present device shows many advantages during use. Specifically, by starting the first motor 22, the first screw rod 23 can be driven to rotate. Since the threads at both ends of the first screw rod 23 rotate in opposite directions, the slider 24 can be synchronously driven to slide smoothly on the inner side of the cross rail 21 when it rotates. Then, the movement of the slider 24 drives the clamping members 25 to displace each other. After the bearing body is placed on the top of the placement plate 26, during the mutual displacement of the fixing frame 251, the clamping frame 252 on the inner side of the fixing frame 251 can clamp the bearing to be processed. It is worth mentioning that the clamping frame 252 is set in a V shape. This ingenious design enables the present device to accurately position and clamp bearings of different sizes, greatly improving the convenience of the present device during the overall use, and significantly enhancing the adaptability of the present device during the processing process. Whether it is a small bearing or a large bearing, it can be stably clamped in the present device, laying a solid foundation for subsequent processing operations.

[0032] By setting up the polishing mechanism 3, the device can play a powerful role during use. First, the second motor 34 is started to run. The second motor 34 can drive the second screw rod 33 to rotate. Through the rotation of the second screw rod 33, the sliding block 351 can be driven to slide flexibly inside the top rail 32. Since the two second motors 34 and the second screw rod 33 are independently provided, during use, the second motor 34 can cooperate with the second screw rod 33 to drive the two polishing wheels 355 to move independently. During the processing, the electric push rod 353 can be started to push the polishing wheel 355 downward. At this time, The precise control of the second motor 34 can cause one polishing wheel 355 to fit closely to the outside of the bearing, while the other polishing wheel 355 can be inserted into the inside of the bearing. Then, the fourth motor 354 is started to run, and the fourth motor 354 can drive the polishing wheel 355 to rotate at high speed. When the two polishing wheels 355 rotate, they can respectively fit the inner wall and outer wall of the bearing for polishing. It can be seen that the device as a whole can polish the outer surface and inner wall of the bearing at the same time, which greatly improves the overall polishing performance of the device and provides a strong guarantee for efficient and high-quality bearing processing.
